Description

  The present invention relates to a vegetation mat for wild grass.

  Conventionally, at least seeds of wild turf before germination are stacked on a base portion formed of paper as this kind of material, and a porous plastic film is stacked thereon with water retaining or moisturizing members interposed therebetween, and the whole is integrated. The plastic film is made of polyethylene, and the seeds are not blown away by wind and rain or do not flow out due to the slope of the ground, and can be germinated and vegetated relatively easily at a desired location. Is known to be protected and cured because it is covered with a plastic film, and can be prevented from being directly affected by the outside air temperature (for example, Patent Document 1).

JP 2007-56 A

  In the prior art, the water retaining or moisturizing member interposed between the seed and the plastic film is formed of paper, so there is a limit to the water retaining or moisturizing member properties. Moreover, when a plastic film should exist, there existed a possibility that a seed might be blown away by the wind and rain.

  The problem to be solved is that in the vegetation mat formed by superimposing at least the seeds of wild turf before germination on the base part formed of paper and overlaying the plastic film on the upper surface, water retention or Moisturizing properties can be improved, and even if the plastic film is damaged, the seeds are hardly blown away by wind and rain.

  In order to achieve the above object, the invention of claim 1 is characterized in that at least seeds of wild turf before germination are stacked on a base portion made of paper, and a porous plastic film is formed on the upper surface via a nonwoven fabric made of cellulose. It is a vegetation mat characterized by being formed by integrating the whole.

  According to the invention of claim 1, the water retaining property and the moisture retaining member property can be improved by the nonwoven fabric made of cellulose, and the seed can be protected even if the plastic film is broken.

It is the perspective view which expanded a part which shows Example 1 of this invention. It is sectional drawing which expanded a part at the time of the installation. It is sectional drawing to which a part after the installation was expanded.

  Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all the configurations described below are not necessarily essential requirements of the present invention.

  1 to 3 show a first embodiment. A vegetation mat 1 includes a paper base portion 2, a vegetation portion layer 3 placed on the base portion 2, and a vegetation portion layer 3 placed on the vegetation portion layer 3. A plastic film 4 having a hole is laminated, and the whole is stitched with a thread 5. The overall size is a width of 0.9 to 1 × length of about 1 to 10 m. And between the vegetation part layer 3 and the plastic film 4, the 2nd paper 2A as water retention or a moisture retention member, and the nonwoven fabric 6 which consists of cellulose interpose.

  The paper base portion 2 is, for example, paper having a transparent density, and a vegetation layer 3 on the base portion 2 is filled with seeds 7 of wild grass before germination, fertilizer 8 and further water retaining or And the vegetation layer 3 is laminated on the base 2. The plastic film 4 is made of polyethylene and has a thickness of about 20 to 40 μm, preferably 30 μm ± 4.8 μm, and a width (diameter) with an interval L of about 5 to 30 mm, preferably about 16 to 20 mm. ) A hole 10 having a W of about 0.5 to 2 mm, preferably 1 to 1.3 mm, is formed so as to penetrate in the vertical direction. Further, the second paper 2A as the water retaining or moisturizing member has a density that is transparent. The seeds 7 do not overlap one above the other, and are arranged so that at least an interval equal to or longer than the length of the seeds 7 (for example, 5 mm) can be maintained if they are arranged evenly.

  The non-woven fabric 6 made of cellulose is formed by a 100% cellulose spunbond method in which a cotton linter, which is a short fiber grown at the root of a seed from which cotton has been removed from real cotton, is used as a raw material and discharged into a long fiber. It is a no-binder and is formed in a net shape that penetrates the hole 6A in the vertical direction.

  Next, a manufacturing method will be described. First, the seed 7 is previously immersed in an acidic solution such as a nitric acid solution to remove the waxy coating on the surface of the seed. And the mixture of the seed 7, the fertilizer 8, the water retention or the moisturizing agent 9 from which the film has been removed is stacked almost uniformly on the paper base 2 cut to a predetermined size. Further, the second paper 2A is overlaid on the mixture, the second paper 2A and further the non-woven fabric 6 are overlaid, and the plastic film 4 is overlaid, and then the base portion 2, the second paper, the non-woven fabric 6, and The seeds 7 and the like are sandwiched by the plastic film 4 so as to be integrated with each other. The sheet-like vegetation mat 1 thus integrated is wound and stored with a width X of about 1 m and a length Y of about 10 m.

  Next, the operation of the above configuration will be described. As shown in FIG. 2, a vegetation mat 1 is laid on the ground 11 such as a slope and a flat surface, and a pile 12 is driven from above the vegetation mat 1 so as not to be blown off by wind. In the vegetation mat 1 thus installed, for example, germination occurs when the accumulated temperature reaches 300 to 400 ° C., and the roots are rooted on the ground 11 through the base portion 2, while the buds are the second paper 2 A and the nonwoven fabric 6. It reaches the lower surface of the plastic film 4 through. At the time of such germination, air is supplied to the seeds from the hole 10 through the slight gap between the second paper 2A and the nonwoven fabric 6 as shown by the arrow A. On the other hand, moisture is supplied by artificial watering or natural rain. This moisture supply is supplied in the same manner as the arrow A through the hole 10 through a slight gap between the second paper 2A and the nonwoven fabric 6. Even if the water is evaporated by solar heat, a part of the moisture is released to the atmosphere through a slight gap or hole 10 between the second paper 2A and the nonwoven fabric 6 in the direction opposite to the arrow A, but it is almost taken away from the surface. The moisture M is absorbed by the second paper 2A and stored inside the plastic film 4 to take measures against water shortage. As described above, most of the moisture M is accumulated inside the plastic film 4 and is not released into the atmosphere. As a result, moderate humidity and further temperature are maintained below the plastic film 4, that is, around the seed 7, contributing after germination, and seed growth can be performed well.

  After the wild turf has germinated and rooted in this manner, the base portion 2 and the second paper 2A are naturally melted and integrated with the ground 11 to return naturally as shown in FIG. Wild grass stalks and leaves are cultivated between the ground 11 side and the plastic film 4. Even at this time, the moisture M is stored as water droplets inside the plastic film 4 by the moisture taken away from the ground surface by sunlight during the daytime, thus taking measures against water shortage. For example, the plastic film 4 is removed together with the piles 12 when the number of leaves of the wild turf becomes, for example, about 4 to 6, and the turf is shown to further grow.

  As described above, in the above-described embodiment, as described above, in the above-described embodiment, at least the seed 7 of the wild lawn before germination is superimposed on the base portion 2 made of paper, and the nonwoven fabric 6 made of cellulose is placed on the upper surface thereof. The following effects are produced by stacking the perforated plastic film 4 and integrating the whole.

  Since the nonwoven fabric 6 made of cellulose is decomposed by bacteria and reduced to soil, it does not naturally decompose and leave a residue.

  Moreover, in the nonwoven fabric 6 which does not use the said paste and resin, the water absorption and water retention of about 15 times its own weight can be exhibited, and drying can be prevented.

  In addition, the use of the nonwoven fabric 6 can soften the strong sunlight during the day, while at the same time serving as a heat retaining agent at night.

  In addition, the non-woven fabric 6 has a relatively low strength. Therefore, even if the turf and leaves of the wild turf stretch and hit the non-woven fabric 6, the stalks and leaves can penetrate the non-woven fabric 6. There is no loss of growth.

  Furthermore, since the non-woven fabric 6 has a relatively large stretchability, it can be stretched and stretched during construction.

  As described above, the vegetation mat for wild turf according to the present invention can be applied to various uses such as turfing of grounds in various schools, turf green areas, golf courses, or gardens of private houses.
